Impact of Guideline-Directed Medical Therapy on Systolic Blood Pressure and Cardiovascular Outcomes in Patients with Heart Failure and Low Blood Pressure: A Systematic Review and Meta-Analysis

Eur J Heart FailPublished

  • Systematic review and meta-analysis of randomised trials

Authors' conclusion

Guideline-directed medical therapy is associated with a negligible decrease in SBP, but can provide similar cardiovascular benefits in both low and non-low SBP HF patients, with no significant interaction with SBP as to hypotension.

Study context

Population
Heart failure (HF) patients, by baseline systolic BP (SBP) category (low vs non-low)
Participants
84,782 patients · 20 studies
Comparison
Guideline-directed medical therapy (GDMT) vs control, by baseline SBP
Outcome
Longitudinal change of SBP due to GDMT, and risks of CV events by SBP category
